    knowledge of astronomy. A star’s life begins as simply a clump of gas known as a molecular cloud. Molecular clouds are very cold‚ around 10-30 K‚ and have a density of about 300 molecules per cubic centimeter. These clouds are full of hydrogen and helium and often contain heavier elements expelled from a large exploding star known as a supernova. There are over 120 different molecules in molecular clouds including carbon monoxide‚ water‚ ammonia‚ and ethyl alcohol. A protostar is the next step in

    This composes the upper 25% of the planet. Next‚ the hydrogen thins out into the gaseous atmosphere which is 1000 km (620 miles) deep. It is composed mainly of hydrogen and helium with trace amounts of methane‚ water‚ ammonia‚ and hydrogen sulfide. Some scientists believe that there are also polysulphur compounds and phosphine which lend their colors to the clouds. Jupiter also has a faint ring system. It is comprised of one

    Thermodynamic Investigation of the Joule-Thompson Effect and Coefficient Determination for Helium and Carbon Dioxide Niki Spadaro‚ Megan Cheney‚ and Jake Lambeth University of North Florida‚ CHM4410C Fall 2010 The Joule-Thomson coefficient explains the behavior of any real gas when changes in intensive properties‚ such as temperature and pressure‚ occur. The coefficients for helium and carbon dioxide were determined using a Joule-Thomson apparatus that created constant enthalpy within the

    cName: Nicholas Cassel Gen Chem 1210 23 March 2013 Blinded By the Light Abstract: In this experiment we were provided a cereal box spectrometer to observe the emission lines of noble gases and hydrogen. Based on the scale readings on the spectrometer and the Balmer-Rydberg formula‚ their wavelengths and percent error were able to be extrapolated. Based on the literature values‚ the cereal box spectrometer proved its value as a decently accurate spectrometer. Introduction: Every element

    The Life of High Mass Stars High mass stars can be classified as any star that is at least four times the solar mass of our star‚ the sun. They consist of about three percent of all of the stars in the universe‚ but there are still billions and billions of them all over the universe. High mass stars‚ like low mass stars‚ begin to form from clouds of gas and dust in space. They both begin as a protostar and eventually become dense enough to cause hydrogen fusion within them; placing them both on

    occur in which hydrogen fuses to form helium. The star then begins to release energy which stops it from contracting‚ and it causes the star to shine. When a star starts to shine it is called a "main sequence star". A star remains in main sequence depending on its solar mass. A star of about 1 solar mass will remain in main sequence for about 10 billion years. After all of the star’s hydrogen has been used to form helium‚ it begins to cool down and the helium fuses to carbon and the star expands‚

    immiscible solute and solvent are illustrated at right. Helium–oxygen mixtures are sometimes used as the breathing gas in deep-sea diving. At sea level (where the pressure is 1.0 atm)‚ the solubility of pure helium in blood is 0.94 g/mL. What is the solubility of pure helium at a depth of 1500 feet? Pressure increases by 1.0 atm for every 33 feet of depth‚ so at 1500 feet the pressure is 46 atm. (For a helium–oxygen mixture‚ the solubility of helium will depend on its initial partial pressure‚ which
